Effects of Phaeomoniella chlamydospora ana Phaeoacremonium aleophilum on grapevine rootstocks

Abstract

G. A. Diaz, M. Esterio, and J. Auger. 2009. Effects of Phaeomoniella chlamydospora and Phaeoacremonium aleophilum on grapevine rootstocks. Cien. Inv. Agr. 36(3):381-390. Cuttings of five grapevine (Pais vinifera) rootstocks were wounded and immediately inoculated with suspensions (approximately 5x10(3) conidia.mL(-1)) of either Phaeomoniella chlamydospora, Phaeoacremonium aleophilum or a mixture of both species. The presence of these endophyte fungi affected the quality of each of the five rootstocks. Among the roostocks investigated in this study, 1103P and 101-14 MG were less susceptible to the infection caused by P chlamydospora and P aleophillum.
